It should be obvious why sticking toothpicks in there is futile - the clamps too far in. Make sure the mechanism is in the up position before clamping it. Worked GREAT!!! Thank you! I didnt even cut t.. 92 - Lexus Owners Club (USA & Canada) Jun 07, 2005I had the same problem. First I bought a brand new switch, no help. Then I got the wiring diagram and shot the wires. Found a bad ground, so I jumped it and everything worked fine. That worked for about six months then the window failed again. I wound up taking it to the dealer and they replaced the driver's side harness.
